Modular Bolt Action for Firearm Handedness Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional bolt action rifles are limited to either left-handed or right-handed configurations, which is not ideal for left-handed shooters, and existing receivers are designed for single-purpose use, limiting flexibility and increasing storage costs.
Innovation Solution
A modular bolt action system that allows quick and easy conversion between left-handed and right-handed configurations by replacing extraction cams and bolt assemblies, enabling the receiver assembly to accommodate various configurations and future accessories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional bolt action rifle is designed for a single handedness configuration, then the structure is simple and reliable, but it cannot be used by shooters of the opposite handedness
Solution Approach 1:
The bolt action is divided into separable components: a receiver body and interchangeable bolt assemblies. The bolt assemblies are designed with different configurations (left-handed and right-handed) that can be independently selected and attached to the receiver body, allowing handedness conversion without redesigning the entire rifle system.
Solution Approach 2:
The receiver body is designed as a universal platform that can accommodate multiple types of bolt assemblies through standardized interfaces. The receiver includes features such as receiver lugs and extraction cams that work with corresponding bolt assembly features, enabling a single receiver to support both left-handed and right-handed configurations.
2Adaptability or versatility
If multiple completed receiver configurations are manufactured to accommodate different needs, then user flexibility is improved, but storage costs and complexity increase
Solution Approach 1:
The system separates the receiver body from the bolt assembly, allowing users to maintain a single receiver and interchange bolt assemblies based on different shooting needs. This eliminates the need to store multiple complete receiver configurations while still providing versatility through component combination.
Solution Approach 2:
The receiver body serves as a multi-functional platform that can be paired with different bolt assemblies to create various configurations. The standardized interface and receiver lugs enable the same receiver to support multiple bolt assembly types, reducing the total number of receivers needed.
3Adaptability or versatility
If the bolt manipulation space is increased to accommodate larger accessories, then accessory compatibility is improved, but the traditional bolt action design must be reconfigured
Solution Approach 1:
The bolt action is segmented into a receiver body and interchangeable bolt assemblies, allowing the bolt assembly to be redesigned for larger accessory compatibility while the receiver body remains unchanged. This modular approach enables future reconfigurations without affecting the entire system.
Solution Approach 2:
The system allows dynamic reconfiguration of the bolt assembly to accommodate changing accessory requirements. The standardized interface enables users to swap bolt assemblies as needs change, providing adaptability without requiring permanent design changes to the receiver body.

AI summary
A modular bolt action for a bolt action firearm is provided. The bolt action includes a receiver and a bolt assembly, the receiver being reconfigurable in a variety of different ways to accommodate a variety of different bolt assemblies. In this way, the modular bolt action can be reconfigured from a left-handed action to a right-handed action and/or from a two-lug action to a three-lug action. Fabrication of the modular bolt action includes adjusting the receiver to accommodate a desired bolt assembly and engaging such bolt assembly with the receiver.
